'11 Claims. (01. 57-44) This invention relates to the spinning of fibers. and more particularly to a novel method of and apparatus for spinning cotton and other textile yarns.

The general objector the invention is to provide a new and improved method of and apparatus for spinning cotton and other textile yarns, whereby the fibers are more thoroughly separated, paralleled and spun into an appropriately twisted yarn for delivery to a mechanical twister and spooler.

A more particular object is to provide a method and apparatus of the character stated whereby cotton and other textile fibers are pneumatically separated. paralleled and spun into an appropriately twisted yarn for delivery to a mechanical twister and spooler.

A further object is to provide a method and apparatus of the character stated whereby a cleaner yarn is produced.

Other objects and advantages will appear as this specification progresses.

The invention is illustrated in the annexed drawing which forms a part of this specification,

The bale opener l comprises an air chamber I.

a bale supporting platform 8 mounted in said chamber on the upper end oi! an hydraulic plunger 9, an air-Jet nozzle ill in the upper part of said chamber 1, and an outlet funnel ll mounted in the upper part of said chamber opposite the end of said jet nozzle H). The air chamber i may include a hinged cover i2 for its upper end, which end of the chamber is formed with an external flange l3 upon which said cover rests in its closed position, said cover being hinged at oneedge to said flange by a hinge i4, and clamped at its opposite edge to said flange 13, in its closed position, by a clamp IS. The hydraulic plunger 9 extends downwardly from the platform 8 through a bearing 18 in the lower end of the chamber 1 into an hydraulic cylinder 11. The jet nozzle [0 is connected to the remote end of a pipe l8 leading from a high pressure air compressor (not shown) into the upper part of the chamber 1.

The storage cell 2 may be a receptacle of inverted irusto-conical form, constructed with an 2 upper end wall H), but without a lower end wall, and said chamber includes an equalizing valve 20 in the upper end of the cell for opening under a predetermined degree of air pressure and allowing air to escape from the cell, whereby the pressure of the air in the cell is prevented from rising above said predetermined degree.

From the smaller end of the tunnel Ii extends a duct 2! outwardly through the upper part of the bale-opener chamber I and through the upper end wall I9 of the storage cell 2 into the upper end of said cell. I

The separating and adjusting chamber 3 may be a receptacle of cylindrical form tapered from its lower portion to its lower end to a small diameter. The upper end of said chamber is open. but is closed part of the time by a weighted trap door 22, while the lower end of said chamber is constructed with a weighted valve 23 for closing said end part of the time. The separating and adjusting chamber 3 is located with its upper end directly under the lower end of the storage cell 2.

A plurality of air-jet nozzles 24 are extended through the cylindrical wall of the carding chamber 3 at one side of said chamber, and a plurality of nozzles 25 are extended through the cylindrical wall of said chamber at the opposite side of said chamber, which nozzles are respectively spaced longitudinally of the separating and adjusting chamber and are connected, respectively, to pipes 26 and 21, which pipes are connected to a pipe 28 leading from a high pressure air compressor (not shown).

The cyclone chamber 4 may be of double conical formation, with its largest diameter, indicated at 29, nearer its upper end than itslower end. and tapering upwardly and downwardly, respectively, from said largest diameter to a smaller diameter at its upper end 30, corresponding to the diameter of the lower end of the separating and adjusting chamber 3, and to a very small diameter at its lower end 3| of suificient dimensions only to permit a yarn appropriately twisted to pass therethroughand be delivered from said cyclone chamber. Air-jet nozzles 32 and 33 extend substantially tangentially to and slightly downwardly into the cyclone chamber 4 through its conical wall below its largest diameter 29, which nozzles are connected to a pipe 34 leading from a high-pressure airv compressor (not shown). The air-jet nozzles-32 and 33 are at such position to the cyclone chamber 4 that jets of air under high pressure delivered therefrom will give a cyclonic" or swirling motion to the air and the fibers in said cyclone chamber. The cyclone chamber 4 is located with its upper open end 30 directly below the lower reduced end of the separating and adjusting chamber 3.

By means of my apparatus as above described d of spinning fibers into yarn,

The cover l2 oi the cliamberl the bile bpener I being unclamped and swung open on its hinge I I, a bale of cotton 35 is placed upon the raised" with an outlet i which abale of cotton or other platform 8, and said platform-and bale arelowi ered in said chamber by the hydrauliccy'linder' I1 and plunger 9, until the upper side of said bale is below the top of said chamber, whereuponthe' cover I! is swung closed over the top of said chamber and clamped in such position by the clamp [5. A jet of air under high pressure is delivered from the nozzle ll against the upper side of the bale of cotton, whereupon the upper cotton fibers are removed from'said bale and delivered by said airjet into the funnel II and forced through said funnel and the duct 2| into the storage cell 2, opening the weighted trap door 22, from which storage cell said fibers are forced by the jetted air pressure into and through the separating and adjusting chamber 3, opening the weighted valve 23, from which separating and adjusting chamber the carded fibers are forced by the air pressure into and through the cyclonechamber 4, the fibers being separated and adjusted in the separating and adjusting chamber 3 while passing therethrough, by the jets of air delivered by the jet nomles 24 and 25 into said forcing said removed fibers out bale for removing the fibers from the bale and of said chamber through said outlet.

.-'-7;"Apparatus including a chamber provided with an outlet, an elevator platform on which a bale oi cottonor other fibers may be placed, a nozzle through which air under pressure may be jetted upon said bale for removing the fibers from said bale and forcing said removed fibers out of "said chamber through said outlet, and means for operating said elevator platform to maintain said bale in position to be acted upon by the jet of air I from said nozzle.

8. Apparatus including a bale opener for pneumatically removing fibers from a bale, a pneumatic fiber separating and adjusting means connected to said bale opener for receiving the removed fibers from said bale opener and separating and adjusting said fibers, and means connected to said carder forreceiving the carded fibers from said carder for pneumatically paralleling and spinning said separated and adjusted fibers into yarn.

i 9. The method comprising pneumatically removing fibers from a bale, pneumatically separatchamber. While passing downwardly through the a cyclone chamber '4 the fibers are given a cyclonic or swirling motion by'the jets of air under high pressure from the jets 32 and 33, whereby the fibers are paralleled, and are appropriately twisted into yarn at the lower restricted end of the cyclone chamber. from which end of said chamber the yarn is delivered to the mechanical twister 5, whichistabilizes the twist oi the yarn and delivers saidtwisted yarn to the sbo l r 8, which winds said yarn onto spools, tubes or cones in the conventional manner.

1. Apparatus including a cyclone chamber'into' which cotton or other fibers may be introduced, said chamber being formed with a reduced open end, and air nozzles extending tangentially into and toward said reduced end of said chamber for directing jets of air under high pressure into said chamber for subjecting the cotton and other fibers to a swirling and conical spiral motion for paralleling and spinning said fibers into yarn.
